Summary:
Features include thin to rather thick, waxy-gelatinous-mucous fruitbodies that are colorless, pinkish, grayish, or somewhat olive to lead-colored, the surface waxy and bumpy or even, growth on wood, and microscopic characters including basidia arising from erect hyphae of rather large diameter.

Microscopic:
SPORES 6-10 x 4-6 microns, nearly round to ovate, white in mass; PROBASIDIA clavate to clavate-capitate, epibasidia 4 or more, finally ovate with a long cylindric or somewhat subulate [awl-shaped] filament tipped with a distinct sterigma; GLOEOCYSTIDIA lacking; HYPHAE erect, branching, with or without clamp connections, (Martin, G.W.), SPORES (5)6-10(12) x 4-6(8) microns, nearly round to ovate; BASIDIA becoming 8-18(30) x (4.5)6-9(12) microns, each usually producing 4 epibasidia, 9-15 x 2.5-5 microns; HYPHAE 2-7 microns wide, erect, branching, thin-walled, (Klett), spores 3.9-5.2 x 5.9-9.1 microns, nearly round to somewhat cylindric; basidia arising from erect hyphae of rather large diameter, a helpful character in identification, (Olive(3)), SPORES 5.9-8.4 x 4.5-5.9 microns, mostly nearly round to obovate, germinating by repetition; BASIDIA mostly in fascicles, forming a rather compact hymenium, 10.4-17.1 x 8.1-9.6 microns, clavate or clavate-capitate, epibasidia (2)4, 8.1-12.6 x 6.3-7.2 microns, (Olive(5))

Notes:
The distribution includes ON, GA, IA, LA, MN, OH, WY, HI, and Europe including Poland, (Martin, G.W.). It also occurs in NC, NY, TN, and VT, (Ginns). There are collections from BC identified by R. Bandoni at the University of British Columbia.
